Abstract
The invention discloses a method for penetration cleaning of ultra-fine inorganic powder slurry, relating to the technical field of cleaning of inorganic powder materials. The method is characterized by comprising the following continuous steps of: firstly enabling the powder slurry to pass through the inside or outside of a semi-permeable membrane pipe at a certain pressure so as to enable the powder slurry to be in full contact with the semi-permeable membrane pipe through which impurities and water in the powder slurry can selectively pass, further removing the impurities in the powder slurry, and cleaning the powder slurry. According to the selective passing principle of the semi-permeable membrane pipe, the impurities in the powder slurry can be simply, quickly and effectively filtered; and furthermore, the whole process only needs to provide a certain pressure to the powder slurry, and the pollution to the environment can be avoided, thus the cleaning method is environmental-friendly and energy-saving.
Description
Technical field:
The present invention relates to inorganic powder material cleaning technique field, be specifically related to the method that a kind of ultrafine inorganic powder slurry infiltration is cleaned.
Background technology:
In the preparation and application of powder, because the needs in final performance of product or the forming process, powder stock must pass through some preliminary treatment, and the slagging-off of powder body material cleaning is the critical process that influences powder body material.When preparation superfine powdery material and nano-powder material; The method of current trend is water chemical reduction method, sol-gal process or the like, in the later stage technology of this class methods preparation, all need remove the gred to powdery pulp; Because the particle of powder body material is smaller; The surface can increase, and in solution, than being prone to deposition, has also brought certain difficulty to slagging-off.
In view of above situation, be necessary to provide a kind of method that can clean the ultrafine inorganic powder slurry in fact.
Summary of the invention:
Technical problem to be solved by this invention is to provide a kind of method that can permeate cleaning to the ultrafine inorganic powder slurry.
Technical problem to be solved by this invention adopts following technical scheme to realize:
The method that a kind of ultrafine inorganic powder slurry infiltration is cleaned; It is characterized in that comprise following continuous step: at first, powdery pulp passes through in pellicle pipe inside or outside with certain pressure; Powdery pulp is fully contacted with the pellicle pipe; Pellicle pipe selectivity is passed through impurity and the water in the powdery pulp, thereby removes the impurity in the powdery pulp, makes powdery pulp obtain cleaning.
The ceramic-film tube that said pellicle pipe is a porous or organic film pipe.
Said pellicle pipe can be arranged in the stainless steel cylinder, stainless steel cylinder is separated into can hold independently space of two of powdery pulp and water impurity.
Said stainless steel cylinder can be processed long tubular, and the single pellicle pipe of set inside also can be processed square box, many pellicle pipes of set inside.
The method that a kind of ultrafine inorganic powder slurry infiltration of the present invention is cleaned; The principle of passing through according to pellicle pipe selectivity; Simply fast and effectively the contaminant filter in the powdery pulp is fallen; And whole process only needs to powdery pulp certain pressure to be provided, and can not pollute environment, is a kind of cleaning method of environmental protection and energy saving.
